. WILD-OATS SEPARATOR.

Application filed June 23, 1920. Serial No. 391,044.

T 0 all whom it may concern.

Be it known that I, FERDINAND W. BUsoH, a citizen of the United States, residing at Berlin, in the county of La Moure and State of North Dakota, have invented certain new and useful Improvements in Wild-Oats Separators; and I do hereby declare the following to be a fullyclear, and exact description of the invention, such as will en'- able others skilled in the artto which it appertains' to make and use the same.

This invention relates to wild oats separators and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide an attachment adapted to be applied to a fanning mill and used for the purpose of separating wild oats from wheat or other grain. as the same passes through the mill.

A further object of the invention is to improve the form of separator whereby the same may be rendered sensitive in order that it may effect the separation from the wheat of other seed or grains which are of different specific gravity or which are different in character as to the condition of inclosing husk or pericarp.

With the above objects in view the wild oats separator comprises a frame adapted to be pivotally connected with the frame of a fanning mill at the end thereof where the blast of an is discharged. A belt is mounted for orbital movement upon the frame of the separator and means are provided for moving the belt from the fan shaft of the mill. The frame may be positioned at various angles with relation to a horizontal and the belt is adapted to receive against its upper run the mixed seed and the blast of air is discharged through the seed whereby the wild oats and seed of less specific gravity are carried up by the belt while the grain or wheat slides down along the upper run of the belt and is recovered in a usual manner. Means are provided for disposing the end portions of the upper run of the belt at an angle with relation to each other and the mixed seed is deposited upon the belt approximately at the apex of the said angle. The blast of air is discharged into the seed at a point immediately below the apex of the angle.

In the accompanying drawings Figure 1 is a side elevation of a fanning mill with the wild oats separator applied thereto,

Fig. 4 is a detail View in side elevation l of the separator, and 1 i F igs. 5 and 6 are detail views in side and edge elevation, respectively, of one of the separator brackets. it As illustratedin the accompanying drawlngs the frame of the fanning millis indicated at 1, the fan shaft at 2 having fan blades 3 mounted thereonin a usual manner. Any suitable means may be provided for rotating the shaft 2. The fan casing is provided with a trunk 4 which is adapted to discharge the blast of air from the fan blades when the fan is in operation. A raddle 5 of usual structure is mounted upon the upper portion of the frame 1 and the may be disposed at various angles with re.

lation to a horizontal. A sprocket wheel 9 is fixed to the shaft 3 and a sprocket wheel 10 isjournaled upon one of the brackets 6. A sprocket chain 11 is trained around the sprocket wheels 9 and 10 and one of i the runs of the chain 11 engages the teeth of a wheel12 which is fixed to the shaft 7 Consequently as the fan shaft 2 is rotated, rotary movement is transmitted to the shaft 7 A roller 13 is journaled at the outer portion of the frame 8 and its shaft is carried in boxes 1 1 which are adjustably mounted in the outer portion of the frame8. A belt 15 is trained around the roller 18 and the intermediate portion of the shaft 7 and its runs move along the frame 8 as the shaft 7 rotates as hereinbefore described.

A crank shaft 16 is journaled in the side members of the frame S-at points between the ends thereof and the crank of the shaft 13 is disposed between the upper and lower.

runs of the belt 15. A roller 17 is loosely journaled upon the crank of the shaft 16 and is 'adapted to bear against the under surface of the upper run of the belt 15. The shaft 16 provided at one end with a handle118 in contact with the blast it-.1

W i is let of the trunk 4: and below the lower edge,

of the raddle 5. Therefore as the mixed grain moves down over the raddle and comes;

which is dis-- the 'air' passes charged from the trunk through the grain V and is of greater specific "ravityfas for instance. wheat, movesdon long): thelower portion oitheupper run or the belt 15 and passes out through the lower portion otthe' fanning j L f to provide port ons of said run at a'nsangle to Itis apparent-thatby ao3us't1ngthetrame mill in a usual manner.
